Javascript TypeError[ERR_INVALID_ARG_TYPE]：该；路径“；参数的类型必须为字符串。接收到对象的实例

我正在使用from a security rules尝试使用Jest对我的Javascript异步函数

async_create_post

（用于firebase HTTP函数

create_post

进行集成测试。涉及的文件具有以下目录结构：

测试文件：

root/tests/handlers/posts.test.js

要测试的文件：

root/functions/handlers/posts.js

教程中的帮助程序代码：

root/tests/rules/helpers.js

下面是涉及的源代码：

posts.test.js

错误消息意味着

path

模块的方法（如

path.join

）希望它的一个参数是字符串，但得到了其他参数

我通过二进制搜索找到了有问题的行，并对程序进行了注释，直到错误消失

---

可能您的某个模块使用了

path

，而您提供了错误的参数。

这里有很多代码，很难判断出哪里出了问题。你能不能把它编辑下来，以显示重现问题的最小代码？大量代码是从在线教程中复制过来的，但我采用了一种文件结构，这种结构是由不同来源的代码组合而成的。我不确定错误消息是否来自我的个人实现或某些安装问题。更新了文章，提供了更多解释。缩小导致问题的特定代码行是调试过程的一部分，这是获得有关堆栈溢出的良好帮助所必需的。如果你发布了数百行代码，那么有人会为你整理所有代码的可能性会大大降低。如果你有一个try-catch块，只需从下到上注释，直到它无法控制台。记录你的错误。但是通读您的代码，我认为data.images可能是object[]，但被视为string[]

async\u create\u post

的底层实现是数据包含一个

images

字符串数组，对于每个字符串，我们希望将其转换为一个映射，带有

uid

，以及初始字符串

url

。我不知道为什么编译器应该关心我是传入对象数组还是字符串数组。毕竟，不管初始输入

images

array中有什么，它都应该创建一个新的数组和一个post记录，对吗？这里有很多代码，很难判断出哪里出了问题。你能不能把它编辑下来，以显示重现问题的最小代码？大量代码是从在线教程中复制过来的，但我采用了一种文件结构，这种结构是由不同来源的代码组合而成的。我不确定错误消息是否来自我的个人实现或某些安装问题。更新了文章，提供了更多解释。缩小导致问题的特定代码行是调试过程的一部分，这是获得有关堆栈溢出的良好帮助所必需的。如果你发布了数百行代码，那么有人会为你整理所有代码的可能性会大大降低。如果你有一个try-catch块，只需从下到上注释，直到它无法控制台。记录你的错误。但是通读您的代码，我认为data.images可能是object[]，但被视为string[]
